Perl Training Australia -
Advanced Parsing with Parse::RecDescent

Perl programmers who are already familiar with the basics of grammar-based
parsing. The techniques presented are not restricted to the specific
applications mentioned, and will be useful to anyone who needs to process
complex structured input of any kind.

This tutorial will show you how to use a range of standard Perl features and
several CPAN modules (in particular, Parse::RecDescent) to decipher and process
a variety of complex data and command formats. It examines some of the more
advanced features of the Parse::RecDescent module and explores the powerful
parsing techniques those features support.

You will learn:

how to design and build self-modifying
parsers to process Apache
configuration files and log data;

how to pull pesky unmatched <P>
tags from HTML;

how to deal with ambiguous data by
parsing it in multiple universes
simultaneously;

how to get Parse::RecDescent to write
most of your grammar for you;

how to parse modular text (e.g. with source
with #includes in it);

how to pre-filter your source code by
tricking Perl into (nearly) parsing
Perl;

how to debug Parse::RecDescent parsers
efficiently and how to improve the
efficiency of your Parse::RecDescent
grammars;
